Been maining him from day one. He has some bad matchups, but he's definitely usable. Gotta get tricky with the mixups throwing in the molten trap. Conditioning them to block the overheads makes it a bit easier to hit them with the trap. Everyone starts immediately blocking low against Firestorm because of the trap and his high strings.
Only buff I'd ask for is the trait to either start at full or (heck I'd even take starting at level 1) or maybe just a faster charge time. I always have to wait for the opponent to clash on second bar before I use it, because sure enough just about every time it gets popped and they haven't clashed, they will if they get caught. Then it's gone for the rest of the match.
Id like to see him used more. He's interesting. I dont know about MagicMan's claim of top 5.. (Id love to hear him line out why he thinks that - no disrespect, would legit like to hear the case presented) but I think he's good.
This is from an observationist standpoint, I dont play FS and know VERY little about him, but when I see him played in higher level situations I always kinda cringe when he pops trait, because his trait doesnt do what people think it does. It doent really regen health, or buff his specials, or make anything launch, or make anything safe, etc. What it actually does is make the very next hit INSTANTLY AND AUTOMATICALLY cause clash. That's what his trait does.
I still dont see why clash resets traits the way it does.
